LDS3985xx

Ultra low drop-low noise BiCMOS 300 mA voltage

regulator for use with very low ESR output capacitor

Features

■ Input voltage from 2.5 V to 6 V

■ Stable with low ESR ceramic capacitors

■ Ultra low dropout voltage (150 mV typ. at 300

mA load, 0.4 mV typ. at 1 mA load)

■ Very low quiescent current (85 µA typ. at no

load, 200 µA typ. at 300 mA load; max 1.5 µA

in off mode)

DFN6

SOT23-5L

■ Guaranteed output current up to 300 mA

■ Wide range of output voltage:

– from 1.25 V to 5.0 V

■ Fast turn-on time: typ. 240 µs

makes it suitable for low power applications and in

battery powered systems. Regulator ground

current increases only slightly in dropout, further

prolonging the battery life. Shutdown logic control

function is available, this means that when the

device is used as local regulator, it is possible to

put a part of the board in standby, decreasing the

total power consumption. Typical applications are

in mobile phone and similar battery powered

wireless systems, portable information

– [C = 2.2 µF, C

= 33 nF and I = 1 mA]

BYP

■ Logic-controlled electronic shutdown

■ Internal current and thermal limit

■ Output low noise voltage 30 µV

over 10 Hz

RMS

to 100 kHz

■ SVR of 55 dB at 1 kHz, 50 dB at 10 kHz

■ Temperature range: - 40 °C to 125 °C

appliances.

Description

The LDS3985xx provides up to 300 mA, from 2.5

V to 6 V input voltage. It is stable with ceramic and

high quality tantalum capacitor. The ultra low drop

voltage, low quiescent current and low noise
